| Effect of a viscous fluid at the end face on the torsional vibration of a rod
Jin Oh Kim/Han Yong Chun
The Journal of Mechanical Science and Technology, vol. 24, no. 2, pp.505-512, 2010
Abstract : This paper deals with the effect of an adjacent viscous fluid on the torsional vibration of a circular rod. The rod is in contact with the
viscous fluid at one end face, and the other end face is torsionally excited by a transducer. The interaction between the torsional vibration
of the rod and the fluid has been studied theoretically. Expressions for the natural frequencies and damping rate of the torsional vibration
have been obtained through exact and approximate solutions.
